Un-hanging the HP Envy 17-DA0013dx for OpenBSD darwinsys.com

A 2026 BIOS update fixed an OpenBSD boot hang on a used HP Envy 17-DA0013dx that the author traced to an ACPI-related CPU attachment panic. The author then installed an OpenBSD drive and reports that the laptop runs OpenBSD-current, with remaining issues including Wi-Fi timeouts, built-in audio and touchscreen behavior with multiple monitors.
